GCC patch to enable -mrelax by default
This is another patch to turn the -mrelax option in GCC by default.
Since PR 10378 and PR 10373 have been fixed, I've tried building GCC with
-mrelaxed enabled by default. The build would stop in
libgcc/config/sh/lib1funcs.S, where GAS would complain that a mova insn is
referring to an unaligned offset.
After applying the following:

GCC (sh-elf C,C++, newlib 2.2.0) can be built successfully.
When compiling a simple C++ program with the resulting toolchain:
#include
int main (void)
{
std::cout << "hello world" << std::endl;
return 0;
}
There are a lot of warnings from LD like:
/usr/local/lib/gcc/sh-elf/5.0.0/../../../../sh-elf/bin/ld:
/usr/local/lib/gcc/sh-elf/5.0.0/../../../../sh-elf/lib/ml/m4/libstdc++.a(locale_init.o):

But linking somehow succeeds. However, the resulting program does not work.
